Abstract :

Gypsum which has a pozzolanic property and silica fume is an industrial by – product which is partially mixed with cement and comparative study is studied in this project. In this project gypsum, silica fume, fine aggregate and coarse aggregate will be used in proportions to the cement concrete mixture. The investigation is carried out with compressive strength test and flexural strength test for cube and beam. The percentage of gypsum in partial replacement cubes is 63%, 73% , 83% and silica fume is 2% i.e.,( 63% of gypsum + 2% of silica fume, 73% of gypsum + 2% of silica fume , 83% of gypsum + 2% of silica fume). And for partial replacement of cement in concrete beams, the percentage of gypsum is 63%, 73%, 83% and silica fume is 2% i.e.,( 63% of gypsum + 2% of silica fume, 73% of gypsum + 2% of silica fume + 83% of gypsum + 2% of silica fume). The overall percentage of gypsum and silica fume is 65%, 75% and 85% on the strength criteria M25 concrete. The comparative study is carried out between conventional and partial replacement beams. The flexural strength tests for beam have to be done and the result will be submitted after the test.
